Ukufikelela kwiiwelds ezikumgangatho ophezulu yeyona njongo iphambili kumatshini wokuwelda indawo yokugcina amandla. Umgangatho we-welding uchaphazela ngokuthe ngqo ukunyaniseka kwesakhiwo kunye nokusebenza kwamacandelo adibeneyo. Eli nqaku lixubusha imiba ephambili ekufuneka iqwalaselwe ukuze kuqinisekiswe umgangatho we-welding kwindawo yokugcina amandla koomatshini be-welding, ibalaselisa ukubaluleka kwezi zinto kunye nokubonelela ngengqiqo ekugcineni imigangatho ye-welding efanelekileyo.
- Ukukhetha i-Electrode: Ukukhetha ii-electrode ezifanelekileyo kubalulekile ekufezekiseni iiwelds ezikumgangatho ophezulu. Izinto ezifana ne-electrode material, ubungakanani, imilo, kunye nemeko yomhlaba kufuneka ithathelwe ingqalelo. Ii-electrode kufuneka zibe ne-conductivity efanelekileyo, ukumelana nokunxiba okuphezulu, kunye nokumila okufanelekileyo ukuququzelela ukuhanjiswa kwamandla okusebenzayo kunye nokugcina umgangatho we-weld ongaguqukiyo. Ukuhlolwa rhoqo kunye nokutshintshwa kwee-electrodes kubalulekile ukukhusela ukuchithwa kwe-electrode kunye nokuqinisekisa ukusebenza okuhambelanayo.
- Iiparamitha zeWelding: Ukuphucula iiparamitha ze-welding kubalulekile ukufezekisa umgangatho ofunekayo we-weld. Iiparamitha ezifana ne-welding yangoku, ixesha le-welding, kunye namandla e-electrode kufuneka anqunywe ngononophelo ngokusekelwe kwiipropati eziphathekayo, ukucwangciswa ngokubambisana, kunye neempawu ze-weld ezifunwayo. Ukulinganisa okufanelekileyo kunye nokubeka iliso kwezi parameters ngexesha lenkqubo ye-welding kunceda ukugcina umgangatho we-weld ongaguqukiyo kunye nokuthintela imiba efana ne-under- or over-welding.
- Ukulungiselela izinto eziphathekayo: Ukulungiswa kwezinto ngokucokisekileyo kubalulekile ekuqinisekiseni umgangatho we-welding. Imiphezulu edibeneyo kufuneka icoceke, ingabikho kwizinto ezingcolisayo, kwaye ilungelelaniswe ngokufanelekileyo ukuqinisekisa ukuba i-metal-to-metal idibene ngokufanelekileyo. Iindlela ezifanelekileyo zokucoca umphezulu, ezifana nokunciphisa kunye nokususa iileyile ze-oxide, kufuneka ziqeshwe ukukhuthaza i-welds eqinile kwaye ethembekileyo. Ukongeza, ukulungelelaniswa okuchanekileyo kunye nokulungelelaniswa kwezinto zokusebenza kunegalelo ekuphuculeni umgangatho we-weld kunye namandla omatshini.
- Ukugcinwa kwe-Electrode: Ukugcinwa rhoqo kwee-electrode kubalulekile ukuqinisekisa umgangatho we-welding ohambelanayo. I-Electrodes kufuneka ihlolwe ngamaxesha athile ukuba inxibe, umonakalo, okanye ungcoliseko. Naziphi na iimpawu zokuthotywa kufuneka ziqwalaselwe ngokukhawuleza ngokucoca, ukulungiswa ngokutsha, okanye ukutshintshwa. Izindlela ezifanelekileyo zokugqoka i-electrode ziyakwazi ukubuyisela isimo se-electrode kunye nemeko yomhlaba, ukuqinisekisa uqhagamshelwano olufanelekileyo kunye nokuhanjiswa kwamandla ngexesha le-welding.
- Ukubeka iliso kwinkqubo kunye noLawulo: Ukuphumeza inkqubo esebenzayo yokubeka iliso kunye nokulawula iinkqubo kunceda ukugcina umgangatho we-welding ongaguqukiyo. Ukujongwa kwexesha lokwenyani kweeparamitha ze-welding, njengangoku, i-voltage, kunye namandla, ivumela ukubonwa kwangoko naluphi na ukuphambuka kumaxabiso afunwayo. Ubuchule bolawulo oluphezulu, olufana neenkqubo zeempendulo ezivaliweyo, zinokuhlengahlengisa ngokuzenzekelayo iiparamitha ze-welding ukuhlawulela ukuhluka kobunzima bezinto eziphathekayo, ukuchasana ngokudibeneyo, okanye ezinye izinto ezinokuchaphazela umgangatho we-weld.
Ukuqinisekisa umgangatho we-welding kwindawo yokugcina amandla koomatshini be-welding kufuneka kuqwalaselwe ngononophelo ukhetho lwe-electrode, iiparamitha ze-welding, ukulungiswa kwezinto eziphathekayo, ukugcinwa kwe-electrode, kunye nokubeka iliso kwinkqubo. Ngokusebenzisa iindlela ezifanelekileyo kunye nokuthobela imigangatho yomgangatho omiselweyo, abaqhubi banokuqhubeka bevelisa i-welds ezikumgangatho ophezulu, okukhokelela kulwakhiwo oluvakalayo kunye noluthembekileyo amacandelo adityanisiweyo. Ukuqwalaselwa kwezi zinto kunegalelo ekusebenzeni ngokubanzi kunye nexesha elide lokugcinwa kwamandla koomatshini be-welding welding.
